The var. intfrmedia is a form connecting N. fallax with i\. definita. 



17. N. fallax Cl. N. Sp. — V. elliptic-lanceolate, with rounded ends. L. 0,o85; B. 0,u32 

 mm. Median line with the terminal fissures in contrary direction. Area very broad, lanceolate. 

 Striae 20 in 0,01 mm., radiate throughout, punctate; puncta about 23 in 0,oi mm. The stria; 

 seem to be crossed near the margin by a fine line. — PI. V f. 27.

This interesting species seems at the first view to be Nar. udndosa, having the outline and 

 marginal striate band of the latter, but a closer inspection shews that it is entirely different, 

 having no rows of stria' along the median line. In fact it is nearly akin to N. definita.

As (tRUXOW has already remarked there is no specific distinction between N. placita and 

 N. Hochstetteri. Nearly akin to N. Hochstetteri is N. Beta, which differs only by its less coarsely 

 punctate striaj. 



19. N. Beta Cl. N. Sp. — V. elliptical, with broad rounded ends. L. 0,043; B. 0,02 5 mm. 

 Median line with the terminal fissures in the same direction. Area broad, lanceolate. Strite 13 

 (middle) to 17 (ends) in 0,oi mm. radiate at the ends, in the middle alternately longer and shorter, 

 finely punctate; puncta about 2i\ in O,oi.mm. — PI. V f. 30.

 radiate throughout, 16 in O.oi mm. punctate; puncta 16 in 0,oi mm. — Pant. Ill PI. V f. 85.

Unknown to the author. It has a considerable likeness to N. mutica var. undulata.
